The bottoming cycle is a cogeneration system in which steam is used first for process heat and then for electric power production. In the plant, a waste-heat recovery boiler recaptures the unused energy and uses it to produce steam to drive a steam turbine generator to produce electricity.

Bottoming cycle plants produce high temperature heat for industrial processes, and then a waste heat recovery boiler feeds an electrical plant. These plants are only used when the industrial process requires high temperatures, such as furnaces for glass and metal manufacturing, so they are less common.
